DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-4 The preferred embodiments of the present application are described in detail so that the advantages and features of the present application can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present application. These implementation modes are only used to illustrate the present invention, and are not intended to limit the present invention.

[0019] The thread trimming transmitting lamp of a sewing machine of the present application comprises a shell 10, a thread trimming button 12, a front infrared transmitting tube 13, a middle infrared transmitting tube 14, a rear infrared transmitting tube 15, a lighting lamp 16, a Hall circuit board 17, a PCB board 18, a Hall 19, a magnetic body 20 and a spring 11, etc. The thread trimming transmitting lamp of the present application can be used to realize manual thread trimming of the sewing machine and to sense the position information of the sewing material, and has a high practical value.

[0020] The housing 10 is composed of an upper cover 101 and a lower cover 102. The upper cover 101 is fixed on the lower cover 102 to form a whole. The housing 10 can be fixed on the overlock sewing machine as a whole. The lower cover 102 is equipped with a thread trimming button 12, a front infrared emitting tube 13, a middle infrared emitting tube 14, a rear infrared emitting tube 15, a lighting lamp 16, a Hall circuit board 17, a PCB board 18, a Hall 19 and a magnetic body 20.

[0021] The thread trimming button 12 has a pushing portion 121, a pressing panel 122, a limiting portion 123 and a magnetic body mounting portion 124. A magnetic body 20 is fixed on the magnetic body mounting portion 124. The pushing portion 121 of the thread trimming button 12 is used to pass through the yielding portion 1013 of the lower cover 102. The Hall circuit board 17 is vertically arranged against the side of the thread trimming button 12, so that the interior appears neat and easy to assemble. The Hall circuit board 17 is provided with a Hall 19, and the Hall 19 is located within the range of the magnetic force of the magnetic body 20. A spring 11 is arranged inside the limiting portion 123. Specifically, the front end of the spring 11 abuts against the inner wall of the limiting portion 123, and the rear end of the spring 11 abuts against the vertical plate 1011 of the lower cover 102. When the pressing panel 122 of the thread trimming button 12 is pressed, the spring 11 is compressed, the magnetic body 20 moves and approaches the Hall 19, causing a voltage change in the Hall 19, and the overlock sewing machine starts the thread trimming action through this voltage change, realizing the thread trimming action of the overlock sewing machine in the manual state. When the pressing panel 122 is released, the spring 11 is reset, the magnetic body 20 is away from the Hall 19, and the voltage value of the Hall 19 does not fluctuate, and the next thread trimming action can be waited for.

[0022] The above-mentioned PCB board 18 is arranged at the bottom of the lower cover 102, and the above-mentioned PCB board 18 is provided with a front infrared emitting tube 13, a middle infrared emitting tube 14, a rear infrared emitting tube 15 and an illuminating lamp 16. The illuminating lamp 16 is always on when the overlock sewing machine is working. The front infrared emitting tube 13, the middle infrared emitting tube 14, the rear infrared emitting tube 15 and the illuminating lamp 16 pass through the bottom plate 1012 inside the lower cover 102, which can improve the reliability of power supply and transmission signal of the PCB board 18 and several emitting tubes, and has high practicality. The front infrared emitting tube 13, the middle infrared emitting tube 14 and the rear infrared emitting tube 15 are provided with corresponding receiving tubes (the receiving tubes are not shown in the accompanying drawings) on the needle plate of the overlock sewing machine. The front infrared emitting tube 13, the middle infrared emitting tube 14 and the rear infrared emitting tube 15 cooperate with the corresponding receiving tubes to sense the position information of the sewing material, and the overlock sewing machine can issue different sewing commands at different positions of the sewing material.
